Specification of Letters Patent.

Patented Nov. 17, 1908.

Application filed March 28, 1907, Serial No. 366,161. Renewed April 25, 1908. Serial No. 429,250.

Be it known that I, Josnrn KLEIDMANN, a subject of the Czar of Russia, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Attachment for FeedingMachines, of which the following is a full, clear, and exact description. 4

This invention relates to attachments for feeding machines, and is particularly useful in connection with devices of this character used for the purpose of feeding sheets of paper into printing presses, ruling-machines and the like.

The object of the invention is to provide a device of this character adapted for use in connection with feeding machines, and by means of which the table carrying the stack of sheets of paper or the like is elevated as required, when the sheets are being segregated and fed into the printing press or other machine.

A further object of the invention is to provide a device of this character by means of which the table is automatically elevated as the stack of sheets upon the table decreases, and by means of which a gradual and uniform upward pull is exerted upon the table atdifi'erent points of the same.

The invention consists in the construction and combination of parts to be more particularly described hereinafter and I fully set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specifi cation, in which Flgure 1 1s a side elevation of a feeding machine having my attachment, and showing parts in cross-section; Fig. 2 is an end view of the device, showing parts broken away; and Fig. 3 is an endview of a detail. Before proceeding to a more detailed explanation of my invention, it should be understood that to attain accuracy in feeding and adjusting the sheets from the feeding machine to the rinting press, ruling machine or the like, it is necessary that the stack of sheets be maintained 'atisubstantially the same height, to enable the feeding mechan ism to segregate the sheets and pass them from the stack uniformly and accurately.

My invention is applicable to feeding niachines of various types in which a vertically slidable table is used to carry the stacks of sheets.

ings, 1 represents the frame-work of a feeding machine having thenprights 2 and 3, between which is slidably mounted a table 4. Rotatably mounted upon the uprights are grooved pulleys 5 and 6, and double grooved pulleys 7 and S. An endless line 9 comprising a cord or other suitable member is arranged between the supports at each side of the table and each line has upwardly disposed loops 10 and 11 passing over the pulleys 5 and 6, respectively, and over the double pulleys 7 and 8. Similar runs 12 and 13 of the upwardly-disposed loops 10 and 11 are rigidly secured to the table 4. As the runs of the upward loops of the endless line which is secured to the table 4 move rated, a like pull is exerted upon the table at four different points when the table is moved upwardly or when one of the runs secured to the table is moved upwardly. By this arrangement the sliding movement of the table is smooth, and there is no possibility of jamming the sliding table in its guides.

The similar uprights 3 have lateral extensions 15 in-which is rotatably mounted a shaft 16. The shaft 1.6 carries a member 17 mounted to swing thereupon and having an arm 18 provided with a roller 19 adapted to engage the stack of sheets 20 and normally are fed from the stack by means of proper mechanism 25 over the lip 21 on to a feed the printing press or other machine. The inember 17 further has an arm 23 at an angle with the arm 18 and having at its end a roller 24.

A second shaft 26 is rotatably mounted upon the similar opposite uprights 3 and has at one end a sprocket 27. By means of the sprocket 27 and a chain 28 the shaft 26 is operated from the driving ,mechanism of the printing press or other in aclnne to which shaft 26 is acam 29 engaging with the roller 1 24 of the member 17 and having a recess 30 1 adapted to receive the roller 24. A second Referring more particularly to the draw to rest upon the top of the stack. The sheets conveyer 22, which transports the sheets to in the same direction when the table is elemy invention is applied. Rigid upon the shaft 33 between the worms 34 is a lever 35 the shafts are having a lateral extension 36 engaging the cam 31, the recess'32 of which is adapted to receive the extension 36. Beyond the extension 36 the lever has a laterally disposed end 37 carrying a'lateral integral pin 38 engaging with the arm 23 of the member 17 and resting normally thereagainst. At the opposite end of the lever is a pawl 39 engaging with a ratchet-wheel 40 rigidly mounted upon the shaft 33 and pressed normally against the ratchet wheel 40 by means of a leaf spring 41 secured to the lever by means of a screw 42.

The upper ends of the uprights 3 are laterally disposed and form bearings 43 in which are mounted shafts 44. Rigid with gears 45 in mesh with the Worms 34 upon the shaft 33. The shafts 44 extend beyond the bearings 43 and have Y rigid pulleys 46, to each of whichis secured 30 a line'or cord 47. The line 47 passes under pulleys 48 rotatably mounted upon the table and has the opposite end secured to a shaft 49 mounted in extensions 50 of the uprights .3. A pawl 51 is carried by the shaft 49 and engages with the ratchet-wheel 40, preventing the rotation of the ratchet-wheel in one direction. p

The operation of the device is as follows:

The roller 19 at the end of the arm 18 normally rests upon the top of the stack of sheets and holds the member 17 in a normal position. As the height of the stack is decreased the roller 19 no longer is in contact with the top. of the stack though the member 17 is still held in a normal position by the cam 29 until the rotation of the latter carries the recess 30 into a position such that the roller 24 on the arm 23 can slide into the recess and thus permit the .member 17 to swing downward about the shaft 16, the Weight of the arm 23 being sufiicient to operate the member. When the arm 23 is in a depressed position the lever 35 is in a 'ment withthe arm of the cam 31 is such thatthe extension 36* similarly depressed position, the weight of the lever maintaining the pin 38 in engage- 23, provided the position of the lever is located in the recess 32 of the cam. The arrangement of the cams upon the shaft .26 is such that when the arm 23 of the member 17 is in the de'ressed ositionin the recess 30, the'extension 36 o the lever 35 isalsoin en agement with the recess 32 of the cam 311 he lever is actuated by gravity, as the lower-end is greater in pivoted lever eoeeee weight than the upper. As the lever swings about the. shaft 33 the pawl 39 is 'raised and slips into engagement .with the next adjacent tooth of the ratchet wheel 40, the latter being held immovable in one direction by means of the pawl 51. As the cam 31 revolves with the shaft 26, the lever 35 is gradually raised by the lobe of the cam and in swinging about the shaft 33 the lever turns the ratchet-wheel 40 and consequently the shaft'33. This in turn through the worms and gears, rotates the shafts 44 and these, by means of the pulleys and the lines 47 raise the table, Whereu on the roller 19 at the end of the arm 18 o the member 17 again comes into engagement with the top of the stack of sheets. The lobe of the cam 29 holds the member 17 in the normal position and thus the table will be raised only when the member is not held in its normal position either by the stack of sheets itself, or by the cam 29. Thus two conditions must be fulfilled beforethe table is raised: The stack of sheets must be lower than the roller 19,'and the recess 30 of the position to receive the,

cam 29 must be in roller 24.
